In our previous article, we've gained insight on the origins of attacks and targeted accounts with a classic pie chart. This time, we would like to have a visual way to represent and understand a typical day of brute force attempts. We could picture that as a world map where a country lights up when an attacker from this country tries to gain access to the honeypot.
This article explains the new features in Python 3.3, compared to 3.2.

This package creates an environment for graphics applications that closely resembles that of the Processing system. It's goal is to implement Processing's friendly graphics functions and interaction model in Python. The pyprocessing backend is built upon OpenGL and Pyglet, which provide the actual graphics rendering. Since these are multiplatform, so is pyprocessing.
